For an upcoming symphonic concert we have 7 DSLRs and a friend of ours has two HPX370s. The issue with the DSLRs is that they can’t zoom live which is very crucial for this production. We wanted to use the 370s to accomplish this.
You can do this the cheap way which I do all the time and it works fine. Adapt the xlr to bnc using a cable and feed that to a regular audio da. Just make sure there Is no distortion and you should be good to go. You can also use a y splitter but at long distances that might be a problem
I have occasionally gotten this with tape based capture (actually a lot) but I thought that solid state was supposed to be impervious to this crap. Is it possible that the capture system is inducing this?
